ON-SITE FOAMED URETHANE TYPE TERMITE PREVENTION HEAT INSULATION MATERIAL, ITS EVALUATION METHOD, AND RAW MATERIAL LIQUID FOR TERMITE PREVENTION HEAT INSULATION MATERIAL

摘要

To provide a heat insulation material which maintains termite prevention for a long term with high termite prevention performance and environment-friendly and human-friendly termite prevention.SOLUTION: A termite prevention heat insulation material is an on-site foamed urethane type termite prevention heat insulation material comprising a foam obtained by mixing a first liquid and a second liquid. The first liquid is an isocyanate component liquid and the second liquid is a mixture of a polyol component liquid, a permethrin solution and an aqueous borate solution. For the solvent constituting the permethrin solution, it is preferable to use a flame retardant usable for the polyol component liquid.SELECTED DRAWING: Figure 2
